The water system in the tower ladder is one of the most versatile weapons in the FDNY arsenal and members should understand how it works as well as the proper communications when operating a tower ladder. Which point made below regarding the water system and communications is not entirely correct?
Select one:
a. A test of the intercom system shall be made each tour and at the initial stages of placing the tower ladder into operation.
b. The intercom system should be the primary means of communication between the bucket and the pedestal as it is the most effective and will limit radio traffic on the HT tactical channel.
c. When communicating between the pedestal and the bucket members will hear terms such as raise, lower, extend, and retract. The reference point when using these terms is always the bucket position.
d. The platform monitor is permanently mounted to the front of the tower ladder bucket and permits 360 degrees of coverage. The water system hookup consists of a 3” x 3” gated inlet and a 4 ½” ungated inlet.
C
(1.4 1.5) Should say “the reference point is always the pedestal and not the bucket position.
The correct answer is: When communicating between the pedestal and the bucket members will hear terms such as raise, lower, extend, and retract. The reference point when using these terms is always the bucket position.
Inspection of the tower ladder is crucial to ensure safe and effective operations. The tower ladder bulletin lists many checks that need to be completed on a routine basis. From the list below please choose which safety check must be conducted each tour?
Select one:
a. Check to make sure that the platform is level.
b. Look for evidence of hydraulic leaks at all connections.
c. Check the monitor for proper movement and the presence of the stream shaper and stacked tips.

(Ch. 7) The book says that this should be done every tour while the rest of the checks should be done DAILY.
The correct answer is: Check the position of the platform control switch on the pedestal to ensure that is not engaged.
Arriving first due allows the tower ladder to attain the best position for initial operations. Officer and LCC’s should maintain situational awareness in order to not impede the accessibility of hydrants for Engine Co. use. Which point listed below regarding tower ladder positioning is not correct?
Select one:
a. The ideal horizontal distance from the center line of the turntable to an objective is 25’. When the center line of the turntable is 32’ from a building there will be sufficient room for the bucket to be dropped below the horizontal with the boom perpendicular to the side of the apparatus.
b. Positioning the tower ladder at a corner building affords coverage on two fronts, enabling operations over a much wider area. Notice shall be taken of overhead and ground level obstructions.
c. The tower ladder may be placed on the sidewalk either fully or partially to reach upper levels or to gain better vantage points. In this situation, verify the condition under the sidewalk and make certain that the jacks and the outriggers are on a firm foundation.
d. Generally, the apparatus should be parallel to the building. If the scrub area of the bucket is reduced by the cab of the apparatus the LCC can correct this by parking the apparatus with front end angled away from the building.
A
(2) The ideal horizontal distance from the center line of the turntable to an objective is 32’. When the center line of the turntable is 25’ from a building there will be sufficient room for the bucket to be dropped below the horizontal with the boom perpendicular to the side of the apparatus.
The correct answer is: The ideal horizontal distance from the center line of the turntable to an objective is 25’. When the center line of the turntable is 32’ from a building there will be sufficient room for the bucket to be dropped below the horizontal with the boom perpendicular to the side of the apparatus.
The type of structure or occupancy will influence initial apparatus positioning and bucket placement. Listed below are four different types of buildings and the proper placement of the tower ladder for each. Which one(s) are not correct? (More than one incorrect).
Select one or more:
a. Taxpayer – Position to operate at street level and protect exposures. Direct the monitor at the ceiling/cockloft area from the street level. The TL can also be used as an observation point at roof level when lightweight construction is encountered.
b. Place of Worship Fire – The tower ladder should always be positioned in front of a place of worship to gain access to the rose window and to be out of the collapse zone.
c. Brownstone/Rowframes – At a brownstone position for top floor VEIS. At a rowframe the tower ladder can potentially cover four (4) row frames. A backing in maneuver may permit booming under the 1st arriving aerial ladder for both types of buildings.
d. Tenements – Position to the fire apartment or floor above or an off window of the fire escape. The presence of a fire escape should not diminish the value of the TL as it can be highly effective when people are present on a fire escape.
B, C
(2.1) TL at a rowframe can potentially cover up to 6 Rowframes., TL should be positioned to cover 2 sides of the building and provide ventilation of the roof and rose window.
The correct answers are: Brownstone/Rowframes – At a brownstone position for top floor VEIS. At a rowframe the tower ladder can potentially cover four (4) row frames. A backing in maneuver may permit booming under the 1st arriving aerial ladder for both types of buildings., Place of Worship Fire – The tower ladder should always be positioned in front of a place of worship to gain access to the rose window and to be out of the collapse zone.
A Captain at chauffeur school was discussing ladder company operations with emphasis on the tower ladder and positioning it on hills. The Captain made the following three (3) statements and was incorrect in which one?
Select one:
a. Position the apparatus parallel to the direction of the slope so that boom operations will be in the “down-hill” direction. If possible, the apparatus should be facing “up-hill”. If facing up-hill, place the turntable past the objective, if facing down-hill place the turntable before the objective.
b. Retracting and/or raising of the boom may be required for “up-hill” operation. By retracting and/or raising the boom, the load will be rotating on a shorter radius, thereby reducing the torque requirements for uphill rotation.
c. All boom operations should be performed delicately and at a low speed while on steep inclines. Sudden stops in maneuvering can cause damage to the apparatus and/or cause the apparatus to skip downhill. All sudden movements should be avoided.
A
(2.4) Position the apparatus parallel to the direction of the slope so that boom operations will be in the “up-hill” direction. If possible, the apparatus should be facing “down-hill”. If facing downhill, place the turntable past the objective, if facing uphill place the turntable before the objective.
The correct answer is: Position the apparatus parallel to the direction of the slope so that boom operations will be in the “down-hill” direction. If possible, the apparatus should be facing “up-hill”. If facing up-hill, place the turntable past the objective, if facing down-hill place the turntable before the objective.
The same Captain continued on with the discussion on tower ladder positioning and made the following four statements. This Captain should re-read the tower ladder bulletin because he was only correct in which statement?
Select one:
a. When positioned in lots, the boom should not be operated at right angles to the chassis at low elevations, it should be operated at narrow angles over the front and rear of the apparatus.
b. When encountering elevated trains or elevated highways, one option is to position the apparatus parallel to the objective, with the pedestal in line with the target, close to the building line.
c. When positioning the tower ladder in a vacant lot, the LCC must conduct a survey for potential collapse zones and voids. The tower ladder must either be in the lot fully or not at all.
d. If live overhead wires fall onto the apparatus members should transmit a “MAYDAY” to notify the IC. The IC should then notify all members that the tower ladder is out of service.
A
(2.5, 2.6) The LCC and the Officer must conduct a survey. The TL can be partially or fully placed in a vacant lot., Place the bucket in line with the target., Transmit an URGENT.
The correct answer is: When positioned in lots, the boom should not be operated at right angles to the chassis at low elevations, it should be operated at narrow angles over the front and rear of the apparatus.
When operations with the tower ladder have concluded there are certain steps that must be taken by the members of the unit to ensure that the tower ladder is safe and ready for the next operation. Which point listed below is not correct?
Select one:
a. After fully retracting the jacks and outriggers the boom shall be re-bedded. The boom has a tendency to rise from the bedded position after the jacks and outriggers have been retracted.
b. At the conclusion of operations, prior to raising the jacks and outriggers, chauffeurs shall personally verify that all manual pins have been removed. Members shall remain alert and stay clear of the immediate area surrounding the TL.
c. When the apparatus is moving in reverse members can either walk alongside the tower ladder or adopt a flanking position to the rear where eye contact with the chauffeur can be maintained.
d. Outriggers should not be raised before verifying that the turntable platform arrow markings meet, thus ensuring that the tower ladder boom is parallel with the apparatus.
C
(2.9) Never walk alongside an apparatus moving in reverse. Instead adopt a flanking position to the rear where eye contact with the LCC can be maintained. Utilization of the apparatus buzzer located in the crew cab along with flashlights at night can be of great assistance.
The correct answer is: When the apparatus is moving in reverse members can either walk alongside the tower ladder or adopt a flanking position to the rear where eye contact with the chauffeur can be maintained.
Members of Tower Ladder 99 were discussing bucket operations during a drill. Which point made during this discussion is not entirely correct?
Select one:
a. Bucket railings are not a substantial part of the bucket and shall not be used as a substantial object when tying off.
b. When a member enters a window from the bucket for VEIS the bucket shall only be moved for rescue and ventilation purposes. When required to reposition the bucket an immediate notification to the members operating inside shall be made.
c. Prior to gaining entry by way of the bucket, members should clear the entire window. Members can place the end of a 6’ hook firmly into the corner of a window sill as a reference point for operating members.
d. When the bucket is properly positioned at a window, immediate notification to the company officer will alert members of the additional means of egress.
B
(Ch. 3 3.1 3.2) When a member enters a window from the bucket for VEIS, the bucket shall not be moved unless required for rescue purposes. When required to reposition the bucket for rescue, immediate notification to the member(s) who entered the window from the bucket shall be made and the bucket returned to the window (or replaced with another aerial/portable ladder) as soon as possible.
The correct answer is: When a member enters a window from the bucket for VEIS the bucket shall only be moved for rescue and ventilation purposes. When required to reposition the bucket an immediate notification to the members operating inside shall be made.
The full capability of the tower ladder will be realized when there are many persons to be removed and/or victims are unconscious, incapacitated, or obese. Tower Ladder 7 has just arrived at a fire on the 4th floor of a 6-story multiple dwelling. As members arrive, they can see a person at a window on the 4th floor. When the OV gets to the window in the bucket he realizes that the victim is obese and will need assistance. In this situation the OV would be most correct to take which action listed below?
Select one:
a. Place the floor of the bucket level with the window sill.
b. Use the middle rail for others so they can easily step into the bucket without straddling the window sill or fire escape.
c. Position the top bucket rail level with the window sill.
d. Notify the company officer inside the fire apartment and have the inside team effect the rescue since the victim is obese.
e. Position the middle of the bucket level with the window sill.
C
(Ch. 3 3.3) Position the top bucket rail level with the window sill or top rail of the fire escape. This is the preferred position for unconscious, incapacitated, or obese victims.
The correct answer is: Position the top bucket rail level with the window sill.
The senior guy in TL100 with 12 years on the job was talking with some junior members of his company. He proceeded to make the following two statements:
Statement 1 – The presence, height, and integrity of parapets and cornices (or lack thereof) are factors that should be considered when placing the bucket to the roof. When placed to the roof for access, the preferred positioning is with the bucket over the roof, parapet, or cornice and the gate parallel to the roofline.
Statement 2 – When multiple trips of the bucket are required to remove a large number of occupant’s, additional tower ladders must be called. When people are removed via the bucket, they must be brought down to the street level to minimize the risk of a civilian falling out of the bucket.
Which statement(s) is/are correct?
Select one:
a. Statement 1 only.
b. Both are correct.
c. Both are incorrect.
d. Statement 2 only.
A
(Ch.3 3.3) Statement 2 should say: When multiple trips of the bucket are required to remove a large number of occupants, removal directly to street level may not be necessary or practical. When time is critical, occupants may be removed to lower levels of the fire building, across the throat to an opposite wing in a “H” Type, to an adjoining roof, fire escape (avoid overloading), or other safe area. When necessary leave a member wit the group of removed occupants to help prevent panic.
The correct answer is: Statement 1 only.
Part of managing a high-stress situation begins with managing oneself. Having an individual plan and constantly rehearsing it builds resilience. Taking a moment to stop, breathe and think will enhance one’s ability to take action in high-stress environments. Which point below is not correct regarding safety when operating in the TL bucket?
Select one:
a. Members in a bucket that is wedged should remain low in the bucket. All members should immediately crouch, sit, or otherwise remain low in the bucket to lower their center of gravity in anticipation of possible sudden, violent movements.
b. If the bucket makes contact with a building, structure or other obstruction and becomes wedged or stuck members in the bucket should verify that all members are secured to a substantial part of the bucket using the installed safety belt, life belt, or personal harness.
c. When no other option is available, members may escape from the bucket by means of the escape ladder in the hinged position. Prior to exiting the bucket, members shall ensure the apparatus remains in P.T.O., the engine is shut down and the escape ladder side rails are raised.
d. Members in a bucket that is wedged should notify the IC by transmitting a “MAYDAY” message. Example: MAYDAY, MAYDAY, MAYDAY.. Ladder 99 OV to Command with a MAYDAY. Upon acknowledgment, transmit: “Ladder 99 OV MAYDAY… the bucket is wedged.”
D
(3.6) Members in a bucket that is wedged should notify the IC by transmitting a “URGENT” message. Example: Urgent, Urgent, Urgent. Ladder 99 OV to Command with an Urgent. Upon acknowledgment, transmit: “Ladder 99 OV Urgent… the bucket is wedged.”
The correct answer is: Members in a bucket that is wedged should notify the IC by transmitting a “MAYDAY” message. Example: MAYDAY, MAYDAY, MAYDAY.. Ladder 99 OV to Command with a MAYDAY. Upon acknowledgment, transmit: “Ladder 99 OV MAYDAY… the bucket is wedged.”
The power saw can be used effectively from the Tower Ladder bucket to open peaked roofs similar to the coffin cut on a tenement roof.

Peaked roof from TL bucket: Make the first cut parallel to the ridge pole. The last cut (#4) is the knock out cut. Four (4) cuts total.
The correct answer is: Peaked roof from the bucket 4 cuts. Coffin cut 7 cuts.
The Tower Ladder provides an excellent platform for overhaul operations including cornice securing/removal and exterior wood sheathing, siding and cockloft overhaul. Which is the only correct point listed below?
Select one:
a. The top of the bucket railing should be positioned slightly above the work area.
b. The boom shall not be used to force timbers or cornices back into a building or onto a roof.
c. The boom can be used to pull or push objects or used as a derrick.
d. When using a power saw from the TL bucket it is preferable to have one member in the bucket to control the bucket and to operate the saw.
B
(3.7) The top of the bucket railing should be positioned slightly below the work area., When using a power saw from the Tower Ladder bucket it is preferable to have one member control the bucket while a second member operates the saw. The power saw shall be lashed to the bucket as a safety measure., The boom shall not be used: To force timbers or cornices back into a building or onto a roof, to pull or push objects, or as a derrick.
The correct answer is: The boom shall not be used to force timbers or cornices back into a building or onto a roof.
Large caliber outside streams generally should not be directed into occupied buildings; members must be warned and occupants should be removed before starting water. In some circumstances, however, fire conditions or a life hazard may demand such use. Which point below is not entirely correct?
Select one:
a. At H-Types with fire showing out windows in the front, courtyard and throat, the TL stream should be directed at the windows in the front first, then advanced toward the courtyard of the building, and finally operated into the throat.
b. Openings made in exterior walls or cornices will often permit stream penetration to the seat of the fire. Power tools should be utilized as necessary. Be aware that time lost breaching walls to reach the cockloft may lead to extension in exposures.
c. The application of a LCS downward into roof openings from an elevated position can be counterproductive. Operating the Tower Ladder stream into roof vent holes is generally ineffective and may result in a prolonged operation.
d. When the fire building is heavily involved or there are multiple floors of fire, LCS delivery should generally start at the lowest level and work upward.
e. A street level attack at taxpayer fires using a LCS to penetrate the ceiling and collapse it, thereby exposing fire in the cockloft, enables the extinguishment of fire therein.
A
At H-Types with fire showing out windows in the front, courtyard and throat, the TL stream should be directed at the windows in the throat first, then advanced toward the front of the building, and finally operated into the front windows.
The correct answer is: At H-Types with fire showing out windows in the front, courtyard and throat, the TL stream should be directed at the windows in the front first, then advanced toward the courtyard of the building, and finally operated into the throat.
There are many special situations where the tower ladder can be utilized to conduct different operations. Listed below are four special situations that may be encountered. Which one is not correct?
Select one:
a. Under no circumstances should a Tower Ladder be used as a crane to “lift” a patient.
b. When using the TL as a high point remove all members from the apparatus, turn the siren to the “on” position, and place the apparatus to the “off” position. In the event someone turns the apparatus on, the siren will alert all members on scene.
c. When breaching an exterior wall from the bucket the cuts in brick walls should be triangular with the vertex angle downward to prevent further collapse. The first cut should be at the mortar joint and second and third cuts should be at the brickwork.
d. The TL may be used as a high point anchor. The preferred location for the high point anchor is under the bucket. Under no circumstances shall the landing pads of the bucket be used as a high point anchor.
e. During periods of heavy snow accumulation, Tower Ladder units should, prior to setting jacks/outriggers on surfaces, clear snow to verify stabilizers are not being lowered onto manholes/vaults.
C
(Chapter 5) When the power saw is being used to cut through brick and concrete, the combination metal/concrete saw blade (diamond blade) shall be used. Electric or pneumatic hammers may also be used for breaching operations from the bucket, when necessary. Cuts in brick walls should be triangular with the vertex angle upward to prevent further collapse. The first and second cuts should be at the brickwork since the easiest cut is at the mortar joint and the blade at this point will usually be worn. Additionally, the cut at the mortar joint may not be necessary since bricks along this plane may be loosened and removed easily with hand tools.
The correct answer is: When breaching an exterior wall from the bucket the cuts in brick walls should be triangular with the vertex angle downward to prevent further collapse. The first cut should be at the mortar joint and second and third cuts should be at the brickwork.
The advantage of an extension ladder is that its height can be adjusted for safe and accurate positioning. Choosing the precise ladder length is not as critical when using an extension ladder as it is when using a straight ladder which has a fixed length. From the following points listed below which are incorrect? (More than 1 incorrect).
Select one or more:
a. When placing a portable ladder alongside a fire escape on a building wall the tip shall be 1’ to 3’ above the fire escape railing. When placing a portable ladder against a fire escape the tip shall be slightly above the fire escape railing.
b. When placing a portable ladder at a window the tip shall be level with window sill. When placing a portable ladder to the roof the tip shall be at least 2 feet above the roof or parapet.
c. When positioning a portable ladder, a 65-75 degree angle allows the ladder to provide its maximum strength and best service.
d. Apparatus arriving at a fire or emergency should not be positioned closer than 35’ to the rear of another Ladder Co. This is to ensure that the 35’ portable ladder can be removed.
e. A simple formula used to obtain a 75 degree angle is to place the base of the ladder at a distance from the vertical plane equal to 1/3 the total working length of the ladder. The working length is the distance from the base of the ladder to the top of the ladder.
D, E
L1, Section 7 20’ straight and/or 35’ extension ladders are carried in the internal slide-in racks on ladder company apparatus. If another apparatus arriving at a fire or emergency is positioned closer than 20’ to the rear of the ladder apparatus, the 20’ straight or the 35’ extension ladder cannot be removed from these racks due to insufficient clearance., To obtain a 75 degree angle, place the base of the ladder at a distance from the vertical plane equal to 1/4 the total working length of the ladder. The working length is the distance from the base to the top of its support.
The correct answers are: Apparatus arriving at a fire or emergency should not be positioned closer than 35’ to the rear of another Ladder Co. This is to ensure that the 35’ portable ladder can be removed., A simple formula used to obtain a 75 degree angle is to place the base of the ladder at a distance from the vertical plane equal to 1/3 the total working length of the ladder. The working length is the distance from the base of the ladder to the top of the ladder.
During a recent day tour members of L99 were drilling with their proby and were discussing portable ladders, mainly their advantages and disadvantages. Which point made during the drill was not entirely correct?
Select one:
a. A protective finish is required on aluminum ladders, as they can dry out and weather with age or sunlight exposure. If a slow oxidizing of the surface occurs, the ladder must be placed out of service for repair and evaluation.
b. Aluminum ladders, in general, are tough. They will dent but will not chip or crack when subjected to severe impact, nor will they fail suddenly because of overloads. They will bend but not break, as wood does.
c. Aluminum ladders readily conduct electricity and heat very rapidly. If an aluminum ladder has been subjected to excessive heat exposure at a fire, even for a brief period, it may have lost its heat treatment. This may affect its load carrying capacity, even though the metal shows no signs of any change.
d. Aluminum ladders are made of a high tensile, heat treated aluminum alloy and can sustain daily wear and tear very well. The aluminum will not weaken with age and it has a long life expectancy.
A
(Lad 1, Sections 3 & 4) No protective finish is required on aluminum ladders, as they will not dry out and weather with age or sunlight exposure. If a slow oxidizing of the surface occurs, it can be polished off.
The correct answer is: A protective finish is required on aluminum ladders, as they can dry out and weather with age or sunlight exposure. If a slow oxidizing of the surface occurs, the ladder must be placed out of service for repair and evaluation.
You are working a day tour in L100 when the LCC tells you that the rig is out of service because it is leaking oil. The mechanic arrives about an hour later and says that the rig must go to the shops and that you will get a spare aerial ladder. After the spare is brought to quarters members are placing all the tools on the spare rig and they tell you that the 35’ ladder will not fit into the ladder rack securely. You then took the following actions listed below and were incorrect in which one?
Select one:
a. You sent a requisition to have the ladder holding devices repaired.
b. You took a mark in the company journal.
c. You made sure the temporary fastenings were checked at the beginning of every tour.
d. You directed the members to secure ladder as safely as possible pending repair or relocation of ladder holding devices by the Fire Tools and Equipment Unit.
e. You notified the Fire Tools and Equipment Unit by telephone.
C
(Ladders 1, Section 5) If ladders cannot be held securely, the Fire Tools and Equipment Unit shall immediately be notified by telephone. A requisition shall be forwarded and an entry made in the company journal. Provision shall be made to secure ladders as safely as possible pending repair or relocation of ladder holding devices by the Fire Tools and Equipment Unit. These temporary fastenings shall be checked after each response.
The correct answer is: You made sure the temporary fastenings were checked at the beginning of every tour.
Whenever a member operates on a ladder of any kind, they must have enough hand control to ensure their safety. This is an absolute necessity when on vertical ladders, such as fire escape drop ladders and gooseneck ladders to the roof. Greater physical effort is needed when using a completely vertical ladder, because a missed step or a slip of the hand will result in a vertical drop and a serious injury. When a member is using a “leg lock” he/she should take which action below?
Select one:
a. The leg performing the locking maneuver should be on the working side. The locking leg is placed over and under the rung that is two rungs above the one on which the member is standing.
b. The leg performing the locking maneuver should be opposite the working side. The locking leg is placed over and under the rung that is two rungs above the one on which the member is standing.
c. The leg performing the locking maneuver should be on the working side. The locking leg is placed over and under the rung that is three rungs above the one on which the member is standing.
d. The leg performing the locking maneuver should be opposite the working side. The locking leg is placed over and under the rung that is one rung above the one on which the member is standing.
B
(8.2) The Leg Lock: The leg performing the locking maneuver is opposite the working side. For example, if the member wants to lean to the right and vent a window, they will lock their left leg on the ladder. To perform the leg lock, the locking leg is placed over and under the rung that is two rungs above the one on which the member is standing. The instep of the locking leg is placed on the beam of the ladder opposite the member’s working side. Using the Personal Harness: The snap hook of the personal harness hooks directly to the ladder rung.
The correct answer is: The leg performing the locking maneuver should be opposite the working side. The locking leg is placed over and under the rung that is two rungs above the one on which the member is standing.
TL99 has an enormous amount of brownstone buildings in their response area and as such are always drilling on these types of buildings. During a recent drill on portable ladder operations in brownstone building, each member made one statement. Which member needs to reread the portable ladder and brownstone bulletins?
Select one:
a. Placing a portable ladder at the window of the small room over the front entrance door will be difficult because of the long high stoop, which may interfere with firefighting operations. Consider placing the ladder at the adjoining window to gain entrance to this small room.
b. In most cases when the fire is on an upper floor, taking the ladder through the first floor (parlor floor) of the fire building and passing it out the rear window to another member in the yard below is faster than using the adjoining building.
c. The rear of the brownstone presents a severe life hazard if there is no fire escape. Portable ladders transported to the rear of the building and properly positioned are safer than a lifesaving rope rescue. They require less staffing and effort.
d. In a brownstone, it is important to take the ladder through with the butt facing the rear of the building. In a row frame, transporting a ladder through the interior of the building to the rear is generally less complicated because there are front and rear doors or window entries at ground level.
B
(10.2) In most cases, taking the ladder through the second floor (parlor floor) of an adjoining brownstone and passing it out the rear window to another member in the yard below is faster than using the fire building.
The correct answer is: In most cases when the fire is on an upper floor, taking the ladder through the first floor (parlor floor) of the fire building and passing it out the rear window to another member in the yard below is faster than using the adjoining building.
Please read the two statements below and choose the correct answer:
Select one:
a. Neither are correct.
b. Statement 1 - When a ladder has been positioned and used by a member to gain entry to a fire building, there is the possibility that he/she will also need it as a means of retreat. The ladder is expected to be there. Therefore, do not move or reposition a ladder used in this manner except if it is necessary to use the ladder for rescue. Members operating in the area the ladder was used to access should be notified regarding its repositioning. The ladder should be returned to its original location or replaced with another ladder as soon as possible.
c. Only statement 2 is correct.
d. Statement 2 - To perform any type of search, portable ladders may be used as a brace where there is a partial or complete collapse of a floor area. The ladders may only be used in groups and not singly. Portable ladders used in bridging operations can span courts, alleys, shafts and similar openings between floors and roofs. Extension ladders must be used either in the nested position or extended position when bridging.
e. Both are correct.
f. Only statement 1 is correct.
F
To perform an emergency search, portable ladders may be used as a brace where there is partial collapse of a floor area. The ladders may be used singly or in groups. Portable ladders used in bridging operations can span courts, alleys, shafts and similar openings between floors and roofs. Extension ladders must be used only in the nested position when bridging.
The correct answer is: Only statement 1 is correct.
